Orange Pi Development Boards Are Raspberry Pi “Clones” based on Allwinner A20 and A31s

After Raspberry Pi, Waxberry Pi, and Banana Pi boards, here come another fruit-named board with Orange Pi. There are actually three models, with Orange Pi and Orange Pi mini based on Allwinner A20, and Orange Pi Plus powered by a quad core Allwinner A31s processor. I’ve drawn a comparison table with the specifications for the three models. Please note that Orange Pi Plus full specifications have not been released yet, so I don’t have all details. Orange Pi Mini Orange Pi Orange Pi Plus SoC Allwinner A20 dual core Cortex A7 processor up to 1GHz with Mali-400 MP2 GPU Allwinner A31s quad core Cortex A7 processor with PowerVR SGX544MP2 GPU System Memory 1 GB DDR3 Storage 2x micro SD slot + SATA NAND Flash + micro SD slot + SATA TBD Video Output HDMI, AV, and DSI I/F HDMI, AV, VGA, and DSI I/F HDMI, AV, and DSI I/F Audio I/O HDMI, […]

Hardkernel ODROID-C1 is a $35 Development Board Powered by Amlogic S805 Quad Core Processor

Amlogic S805 is a quad core Cortex A5 processor which has found it way into low cost devices such as MK808B Plus TV Stick which can be purchased for as low as $30, or full-sized TV box such as MXQ S85 or MINIX NEO X6. All this low cost devices are nice, but the full source code is not available in your want to adapt them to your need. Luckily, Amlogic releases both an Android SDK, and a buildroot for Linux with GPU and Video Processing Unit (VPU) support, so Hardkernel decided to go ahead, designed a board, and has just launched ODROID-C1 quad core development board for just $35, or the exact price of a Raspberry Pi Model B+, but with much greater specs. ODROID-C1 specifications: SoC- Amlogic S805 quad core Cortex-A5 processor with a Mali-450MP2 GPU (2x fragment cores + 2x vertex shader cores) System Memory – 1GB […]

Banana Pi M2 is an Allwinner A31s Quad Core Board with Raspberry Pi Model B+ Form Factor

Banana Pi, and the recently announced Banana Pro, are Android & Linux development boards based on Allwinner A20, with a form factor similar to Raspberry Pi Model B and B+ boards respectively. A new revision of the board is now available with Banana Pi M2 powered by Allwinner A31s quad core processor, and in a form factor similar to R-Pi B+. Banana Pi M2 specifications: SoC – Allwinner A31s quad core Cortex A7 @ 1.0 GHz with PowerVR SGX544MP2 GPU System Memory – 1GB DDR3 Storage – Micro SD slot up to 64GB Connectivity – 10/100/1000 Ethernet, 802.11 b/g/n Wi-Fi (Realtek) Video Output – HDMI, CVBS, and LVDS/RGB header Audio Output – HDMI and 3.5mm stereo jack Camera – CSI connector USB – 2x USB 2.0 host ports + micro USB port (power only) Debugging – UART pins for serial console Expansion Header – 40-pin R-Pi “somewhat” compatible header with […]

Semtech LoRa SX1272 RF Module Enables Up to 30 KM Wireless Range for Arduino, Raspberry Pi, Waspmote, and More

Libelium’s Waspmote is a board based on Atmel ATmega1281 MCU that interfaces with over 80 sensors, and various wireless communication modules, and targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. They have some professional kits for over 3,000 Euros including training, but a more affordable Starter Kit is also available for 199 Euros on Cooking Hacks. But I’m not going to cover Waspmote in details today. I just mention it because of an article on embedded.com mentioning compatibility with a Libelium / Semtech LoRa SX1272 RF module delivering up to 30km range in ideal conditions (and usually 22+ km range in LOS), and about 2km range in urban settings. I previously featured XBee-PRO 900HP RF Module with a 45km range, so the Semtech module is just another option, and it works not only with Waspmote, but also the […]

Suptronics X200 Raspberry Pi Model B+ Expansion Board Adds Wi-Fi, RTC, VGA, optical S/PDIF, USB ports, Servo Support, and More

The Raspberry Pi is a nice little board, but in some cases you may want to add some extra ports. Suptronics released the X100 expansion board for Raspberry Pi Model B last year, and they’ve now come up with a little monster called X200 expansion board for Raspberry Pi Model B+ which adds Wi-Fi, a real-time clock + battery, a VGA port, optical S/PDIF output, 3.5 mm mic and audio jack, servo support (ULN2803), and a few USB ports to the low cost board. Key features of X200 expansion board: Input Voltage – 6V to 21Vdc converted to 5V, 3A via step-down DC/DC converter to power the Raspberry Pi. VGA output – HDMI to VGA converter supporting up to UXGA (1600×1200) and 1080p with 10-bit DAC Audio – 3.5mm MIC in jack, 3.5mm stereo audio jack, S/PDIF output, audio I/O connector (Microphone input and stereo audio amplifier 3.3Wx2) Connectivity – […]

Raspberry Pi Model A+ Board Features a 40-pin GPIO Connector, a micro SD slot, and Improved Power Management

After the Raspberry Pi foundation officially announced Raspberry Pi Model B+ board, it was natural to expect a Model A+ to come soon after. Based on a webpage on Element14 (now down), an update of the cheapest version of the Raspberry Pi could get announced very soon, maybe as soon as Monday. It has specifications very similar to Model A, but replaces the 26-pin GPIO connector, by a 40-pin connector, a micro SD slot takes the place of a full-sized SD slot, and power management has been improved so that it’s more efficient, and can support “power hungry” USB devices. [Update: It’s now officially announced as planned] I’ve drawn a comparison table between the latest two boards: Model B+ vs Model A+. Raspberry Pi Model B+ Raspberry Pi Model A+ SoC Broadcom BCM2835 ARM11 processor @ 700MHz with VideoCore IV GPU System Memory 512 MB (PoP) 256 MB (PoP) Storage […]

Connect Objects Wirelessly, and Create User Interfaces Easily With Xped DeB for Arduino (Crowdfunding)

Xped, an australian startup, has designed an ecosystem comprised of an Arduino shield with NFC and 802.15.4 connectivity, a Raspberry Pi Model B+ based gateway, and DeB browser that generates a user interface in Android, iOS, or Linux based on an XML file stored in an Arduino board. This allows to connect various objects wirelessly, with reduced power consumption thanks to 802.15.4, and to create user interfaces easily with a text file located in your Arduino board. ADRC stands for Auto-Discovery Remote Control, and that’s what Xped ADRC Shield allows thanks to the following hardware specifications: MCU – RM Cortex M3 32-bit microcontroller with 256 KB of FLASH memory. NFC – NDEF Type-2 Tag with bi-directional communications capability. NFP proximity communications technology which is similar to NFC but was developed by Xped to use less than 1,000th of the power and provide faster speeds than NFC. It is mainly used […]
